HENRY HOLLAND, OF DETROIT, MICHIGAN.

TROLLEY-STAN D.

SPECIFICATION formingv part of Letters Patent No. 694,152, dated February 25, 1902.

Application ned August 28,1901. serinnmstts. (roman.)

To all whom it may concern;

Be it known that I, HENRY HOLLAND, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Trolley-Stands; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication. Y

My invention relates to trolley-stands; and it consists in the improvements hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings,

Figure lis an elevation of a trolley-standeni-- bodying my invention, the same being mounted upon a track upon which it is designed to travel, as described in a patent granted to William G. Holmes and myself February 13, 1900. Fig. 2 is a vertical central section of the same, taken in a plane at right-angles to the plane of Fig. l. Fig. 3 is a plan View of the stand, the cover being removed and a part of the flexible canvas disk being broken away. Fig. 4 is a plan View of the same, the cover, canvas disk, and guard-ring being removed.

The same reference letter indicates the lsame part in the dierent views.

The portion of the roof of the car to whichv the lstand is attached is indicated by the letter B B are two pieces of angle-iron running parallel to each other llengthwise of the roof of the car, with one ange of each lying horizontally. The angle-irons B B constitute tracks upon which the trolley-stand travels.

B' B are wheels upon the trolley-stand adapted to roll on top of the tracks B B.

B2 B2 are wheels upon the trolley-stand adapted to pass at the upper part of their peripheries about a quarter of an inch below the horizontal flanges of the tracks B B. The Wheels B2 B2 prevent the trolley-stand from rising from the tracks B B and becoming displaced.

O is a disk forming the base of the trolleystand and provided with an upwardly-extending flange C around its periphery. The wheels B B2 are pivoted upon arbors extending from the plate C. At the center of plate C is an Vupwardly-rising cylindrical lug c. Around the upper edge of the flange O is formed a groove, which is shown-in Fig. 2 as having a semicylindrical cross-section.

D is a plate approximately circular in outline and of a diameter a little less than that of the flange C. There is a circular aperture at the center of the disk D, adapted to pass over the cylindricallug c,and extendingdownward from the plate D around said aperture is an annular projection, as shown in Fig. 2.

d d d d are wheels pivoted upon horizontal arbors extending outward from the periphery of the plate D.

B is a vertically-extending ange rising from the periphery of the plate D..

D2 represents lugs upon the fiange D.

E is a ring, L-shaped in cross-section, having the same diameter as the ange O and having a groove in the lower edge thereof corresponding to the groove in the flange C. The lower edge of the ring E is placed upon the upper edge of the flange C, the grooves in said ring and said flange matching and together forming an annular opening having a circular cross-section. Between the auge C and the ring E is placed an asbestos ring which serves to pack the joint between said ring and said ange.

E represents lugs extending from the ring E, and C2 represents lugs entending from the flange O'. y

Vg represents bolts passing through the lugs E O2 and serving to bind the ring E upon the flange C. The upper part of the ring E extends inward over' the wheels d.

The plate C and ring E are made of castiron and are chilled at the places with which the wheels d will come in contact with them.

F is a canvas disk circular in outline and of a diameter a little less than the diameter ot the ring E and having a circular aperture at its center. The canvas disk lies upon the upper edge of the flange D' concentric therewith, the edge of said canvas extending over the ring E and bending down to rest thereon. The flange D is of such a height that its upper edge extends slightly above the upper edge ot the ring E.

Gis a sheet-metal disk having its outer edge turned downward, as shown most distinctly in Fig. 2. 4The disk G has an aper- IOO ture at the center for the purpose hereinafter described, and the disk G lies upon the canvas disk F.

H is a cast-iron plate of about the diameter of the flange D and having a cylindrical aperture through its center and an annular downwardly-extending flange around said aperture. The plate H is placed upon the disk G above the flange D' and concentric with said flange and said disk, the annular flange at the center of the plate H extending through the center apertures in the disk G and canvas F.

h represents bolts extending through boltholes in the plate H, disk G, and canvas F and engaging with the lugs D2 upon the ange D over the plate D. Nuts arescrewed upon the upper end of the bolts h to bind the plates D and H together, with the disk G and canvas F between them.

M is a spring niakingelectrical contact with the plates C and D.

I is-a socket or casting upon which the trolley-pole will be pivoted.

J J indicates springs for controlling the action of the trolley-pole.

N is a latch loosely secured by the nut n to the base-plate C. When the stand is at one end of its travel, the hook N catches over the end of a track B and prevents the accidental movement of the stand along the track. When the trolley-pole is deflected inthe reverse direction, the stand is slightly tipped up, so that the hook N is released from engagement with the end of the track, allowing the stand to be moved toward the other end of the car.

In putting the above-described trolley-stand together and adapt-ing it to practical operation the following method is employed: A layer of ,lubricating-oil is rst placed upon the plate C within the flange C'. The plate D is then placed concentric with the plate C, the lugs c extending from its center aperture and the wheels D resting upon the plate C f near its periphery and supporting the plate D. The asbestos packing is then placed in thegroove at the upper edge of' the flange C. The ring E is then placed upon the flange C', its lower edge registering with the edge v of said flange and the asbestos packing extending into the groove in the lower edge of said ring. The ring E and plate C are then firmly bound together by bolts t, compressing the asbestos packing e between their edges. The canvas F is then placed upon the upper edge of the flange D and the disk G placed upon the said canvas and the plate H upon the disk G, `the central annular flange of the latter extending through the central apertures to the disk G and canvas F. The plates H and D are then firmly bound together by bolts h, which have been put in p0- sition on the plate D previous to putting the canvas F, disk G, and plate H in position.

It will be noticed that in the above-described device the working parts are always lubricated and well covered with oil, so that rusting will be prevented, and it will not be necessaryto take the stand apart except at very distant intervals of time; that dust is ina large measure excluded from the oil and working parts by the downwardly-extending peripheral portion of the disk G, and what dust does pass through the obstruction formed by the plate G will be prevented from entering to the working parts by the canvas F, the outer edge of which rests upon the upper surface of the ring E. The oil placed upon the plate C cannot escape because of the packed joint between the ring E and the flange C and because of the canvas F preventing a passage over the ring E. The wind passing between the disk G and ring E compresses the air slightly between the two and has a tendency to press the canvas F downward against the upper surface of the ring E.

What I claim is- 1. In a trolley-stand and base, the combination of a plate having a flange rising therefrom and forming a receptacle for lubricating-oil, and a trolley-holding plate provided with wheels at its periphery,said trolley-holding plate being adapted to rest with said wheels upon the first-named plate and to turn thereon within said flange.
